People really need to learn moderation with this game. There are too many people that act like this is a serious addiction. I see it all the time over at MMO, people stating that they need to quit, people glad they did quit. If you are really that addicted to this game you probably have an addictive personality and if you quit, you will likely replace this addiction with something else (i.e. watching TV for 4 hours a night, playing a different game, surfing the web...etc...).
If the game is starting to feel like work, then quit, but if you are having fun and it isn't hurting anyone, who cares. I used to play a lot, and when we had our daughter I cut down to 2 raiding nights a week. It affects my life for only 2 nights, and after she goes to bed. I've never felt the need to quit because I take 2 nights to myself to play the game. I don't understand all the drama over this, like it's some crazy drug that consumes people's lives. Go get hooked on pharms or be an alcoholic, when you end up making your family bankrupt or you end up in a gutter at 5am in the morning, you have a valid concern to get uptight about. A Video game? I don't get why people get so upset about playing them, maybe we need more of those video game boot camps to set people straight.
